ReSharper extends Visual Studio with over 1700 code inspections for C#, VB.NET, ASP.NET, JavaScript, TypeScript and other technologies. For most inspections, ReSharper provides quick-fixes (light bulbs) to improve code in one way or another.

ReSharper helps instantly land at any code in a solution, no matter how large it is. It can also navigate you from any symbol to related code such as implementations of a given interface, extension methods of a class, or usages of a field.

Configure and apply code style whichever way is best for you or your team. Code style and formatting settings for C#, VB.NET, ASP.NET, JavaScript, TypeScript and other languages can be applied in any scope, from a selection to a solution.

ReSharper can create a lot of code for you: from new files and classes to conditional blocks and GUIDs; from methods
and properties
required by an interface being implemented to equality checks and formatting members.

ReSharper Ultimate is a license that combines all individual JetBrains .NET tools, as well as ReSharper C++.
Each ReSharper Ultimate license allows a single developer to use ReSharper, ReSharper C++, dotCover, dotTrace and dotMemory.

ReSharper

Productivity extension to Visual Studio for .NET devs

new

ReSharper C++

A fork of ReSharper that only supports C++

dotTrace

.NET performance profiler

dotCover

.NET unit test runnerand code coverage tool

dotMemory

.NET memory profiler

dotPeek

.NET decompiler & assembly browser (it's free anyway)

Use .NET languages and C++

If a single developer uses Visual Studio to code both in C# (or VB.NET, or TypeScript, or other languages supported by mainline ReSharper) and in C++, they would probably want to have ReSharper help them out in both worlds.

Have profilers readily at hand

Having familiar tools at hand helps confidently solve performance and memory consumption problems as they arise. ReSharper Ultimate includes both dotTrace and dotMemory, making them readily available when it comes to the crunch.

Enjoy uniform maintenance

ReSharper Ultimate always includes a 1-year free upgrade subscription that is aligned across all included products. Upgrade to any new releases for free within a year after purchase, and optionally renew your upgrade subscription in one step.

What ReSharper Users Say

I love ReSharper! Its tightly integrated unit testing makes it a joy to do test-driven development, its automated
refactorings are nothing short of superb and its code suggestions routinely help me write better C#/VB.NET code.

The ultimate Agile tool is ReSharper. It is the one thing for .NET developers that removes fear of change.
Refactoring is just so darn easy that change isn't scary.

ReSharper is an awesome tool. If you're using it you probably agree and if you aren't you should
be. The productivity gains are incredible. The moment you see another developer step
effortlessly through the code you'll agree.
